- Application filed October 18, 1920. Serial No. 417,821.

Be it known that I, FREDERICK C. RUrrnL, a'citizen of the United States,and residing at Grand Rapids, in the county of Kent and StateofMichigan, have invented a new and Improved Celluloid-Coated Cement Body,ofwhich the following is a specificatlon.

This invention consists in a body of concrete or a similar plastic massand a transparent or translucent facing united by pouring the lasticmass agalnst the transparent or trans ucent facing. 4

'It further consists in the details of 0on1 struction illustrated in theaccompanying drawing and particularlypointed out in the claims.

In the drawing, Figures 1 and 2 are perspectives of two concrete slabsfaced with translucent materials.

Similar reference characters refer to like parts in the two views.

Attempts have been made to provide tiles, other slabs of concrete andhollow bodies of concrete and other plastic materials with outersurfaces which can be cleaned, but great difliculty has been metheretofore in the attempt to secure such facings to'the body of theplastic material. In the present case, a slab 1 of concrete is shownprovided with a face 2 of celluloid which may be as thin as desired andwhich may have any-desired tint.

In securing the concrete mass to the facing of celluloid, a sheet ofcheese cloth 3 or other thin fibrous material is attached to thecelluloid by means of a hot iron. which is passed back and forth overthe cheese cloth until it unites with the celluloid. Or the fibrousmaterial may be secured to the celluloid by means of a suitable cementsuchas gums or resins dissolved in acetone, amylacetate, carbontetrachlorid or other volatile After the celluloid has been thusprepared it is placed in the mold for the concrete body and against thebottom or side of the mold and the plastic mass is poured onto oragainst this sheet of celluloid. The

celluloid may be embossed before or afterthe fibrous layer is appliedthereto. The

fibrous layer serves as a bond between the celluloid and the concrete byfurnishing a tooth to which the concrete ma attach. The concrete may bemade up of ortland cement and sand or crushed stone or a mixture ofthese with magnesium or other oxychlorids, and chopped straw, saw dust,

ground cork, or other inert substances may be added if desired- V InFig. 2 I have indicated the layer 2 of celluloid sprinkled with groundsand,

glass, or crystalline rock 4 which is attached to the layer of celluloidby means of any one of the cements above mentioned or by heatingthecelluloid and pressing this ground material into the softened surface.In this case, these crystalline substances form bases upon which thecement in the concrete may crystallize so as to obtain a strong bondbetween them. i

Where the celluloid is to be attached to the outer sides of hollowbodies, the sheet of celluloid will be bent to fit the mold, before orafter being prepared in the manner above stated, after which it isplaced in the mold so that concrete can be poured against it. It is notnecessary to provide sufficient celluloid to cover the entire surface ofa concrete body as smaller pieces, may be attached to limited areas ofsuch bodies.

The finished construction is pleasing in appearance in that it is smoothand bright and when transparent celluloid is employed permits thestructure of the concrete body to be seen, It permits the outer surfaceof the composite body to be thoroughly cleaned, which is impossible withordinary concrete.

While in this description I have used the term celluloid, I do not wishto be restricted to the several celluloids, as any non-crystallinetranslucent material such as bakelite, redmanol, galalith, and similarcompounds may be employed.

The details may all be changed by those skilled in the art withoutdeparting from the spirit of my invention as set forth in the followingclaims.
